I found this on the internet and they only sell in the UK. Does anyone know where I can find something like this? I am making a stilleto boot topper.

Thanks!

The only thing I can suggest is try googling stiletto shoe mold 

Ditto what kakeladi said.  I have a shoe mold kit, but the only thing I use is the heel mold because I don't think it looks very natural.  I think my freehand is much more realistic.
